SJ3,5-N
Inductive Slot Sensor
3.5mm slot-width inductive slot sensor, NAMUR 2-wire NC, SIL2 intrinsic safety, 3kHz response for metal detection
Key Features
- 3.5mm slot width for medium metal marking, covering a wider detection range than the SJ2-N.
- NAMUR two-wire intrinsically safe output; requires a compatible explosion-proof isolation barrier system.
- Up to 3000Hz switching frequency for medium-to-high-speed production line inspection needs
- IP67 rated, stable operation from -25°C to 100°C, built for harsh environments
